https://devzone.nordicsemi.com/f/nordic-q-a/34746/nrf52832-chip-antenna-guidelinesHi I was designing nrf52832 based PCB and using Jhonson&#39;s 2.4ghz antenna. The PCB is 2 layer and I am following the guidelines of chip antenna as given in the datasheet. The final PCB thickness would be 0.6mm so as to decrease the feed line width anden-USTelligent Community 13Fri, 25 May 2018 12:22:46 GMThttps://devzone.nordicsemi.com/thread/133427?ContentTypeID=1Fri, 25 May 2018 12:22:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:37d6a496-f9d0-487f-be62-ce211ce547c2ketiljo<p>1. The matching of the DK antenna is done with the capacitor closes to the antenna. The first two components is the matching network for the radio and must always be there. So you need L1 and C3 in addition to the antenna tuning components from the antenna datasheet.&nbsp;</p> <p>2. Yes, always have ground plane on both layers.&nbsp;</p> <p>3. Yes, no problem. Adjust the dimensions of the transmission line, if ant, to match the PCB thickness and clearance to ground.&nbsp;</p><div style="clear:both;"></div>
